> The ProtobufRpcEngine class doesn't allow for new RpcEngine implementations
> to extend some of its inner classes (e.g. Invoker and
> Server.ProtoBufRpcInvoker). Also, some of its methods are long enough such
> that overriding them would result in a lot of code duplication (e.g.
> Invoker#invoke and Server.ProtoBufRpcInvoker#call).
> When implementing a new RpcEngine, it would be helpful to reuse most of the
> code already in ProtobufRpcEngine. This would allow new fields to be added to
> the RPC header or message with minimal code changes.
